Traditional dwellings as the products of the combined effects of time, space and agency possess both a dynamic nature and historical continuity. With the progression of globalization and urbanization, the patterns of villages in Southwest China have transformed from enclosed, stable and homogeneous into open, dynamic and diverse. As crucial representations of rural spatial reconstruction and cultural evolution, the form and function of traditional dwellings are undergoing profound transformation and reorganization. The introduction of modern building methods and the shift in living concepts and aesthetic preferences intensify the impact on traditional building techniques, leading to a rupture in the traditional dwelling typological system. From a typological perspective, this study analyzes the transformation process and organizational characteristics of the traditional courtyard house prototype, as well as the social structures and cultural logic it reflects, by integrating the family life cycle, spatial concepts, and residential practices of Dai households. The findings indicate that Dai dwellings have undergone a four-phase typological process. The initial transformation was evident in the architectural details of the main rooms. Secondly, the spatial sequence embodying the clan order gradually disintegrated, and spaces with religious functions were continuously weakened, eventually being replaced by modern residential space dominated by standardized functional zoning. Concurrently, the layout of Dai dwellings was simplified from a four-sided courtyard house into a three-sided courtyard house and ultimately transformed into the layout primarily composed of independent, non-courtyard buildings. Its typological process reflects proactive adaptations to modern residential culture. However, this adaptive transition has also undermined the traditional Dai spatial order and cultural meaning, revealing a tension between cultural adaptation and cultural dissolution.
